FIX: New FILESTREAM Filegroup can’t be recognized when you alter a partition function with SPLIT RANGE in SQL Server

Applies to: SQL Server 2012 EnterpriseSQL Server 2012 DeveloperSQL Server 2012 Standard More


Consider the following scenario:
  • You have installed Microsoft SQL Server 2008, Microsoft SQL Server 2008 R2, or Microsoft SQL Server 2012 on a computer.
  • You create a partition function by using RANGE LEFT or RANGE RIGHT function.
  • You create a partition scheme that uses the partition function.
  • The partition scheme references a filegroup that holds FILESTREAM data.
  • You change the partition scheme by using NEXT USED property.
  • You execute ALTER PARTITION FUNCTION statement together with SPLIT RANGE property.
In this scenario, the new range is not correctly mapped to the filegroup that is specified when you alter the partition scheme.


The issue was first fixed in the following cumulative update of SQL Server.

Cumulative Update 2 for SQL Server 2012 SP2

Cumulative Update 11 for SQL Server 2012 SP1

Cumulative Update 13 for SQL Server 2008 R2 SP2

Cumulative Update 17 for SQL Server 2008 SP3
